Chevy offers two capable diesel engines that are the powering force behind several trucks and SUVs in their lineup. Diesel engines are desirable because they deliver high torque at low RPMs, enabling vehicles to easily tow heavy loads or power up steep hills. They also offer better fuel economy compared to traditional gas engines. Now that we’ve established the advantages of diesel, let’s take a closer look at the capabilities of Chevy diesel engines.

Exploring the Power of Chevy Diesel Engines

3.0L Duramax Turbo-Diesel I-6

The 3.0L Duramax Turbo-Diesel I-6 engine was engineered with large SUVs and trucks in mind. Redesigned in 2023, it provides a perfect balance between power and efficiency, delivering high torque where you need it the most, while also providing impressive range and fuel economy. In the 2025 Chevy Suburban, this engine is available in the Z71 trim, where it offers 305 hp and 495 lb-ft of torque, along with best-in-class 728 miles of highway range per tank.

In the Chevy Tahoe, the 3.0L Duramax engine is also available in the Z71 trim, where it provides 305 hp, 495 lb-ft of torque, and pairs with a ten-speed automatic transmission. The engine uses a leaner fuel-to-air mixture than gas engines, resulting in superior EPA estimates of 28 MPG on the highway and 21 MPG in the city. Similar fuel economy ratings are seen in the Suburban, making these two vehicles the most fuel-efficient large SUVs in their class.

6.6L Duramax Turbo-Diesel V-8

While the light-duty Chevy Silverado 1500 offers the 3.0L Duramax engine with the same performance specs as the Chevy Tahoe, the Silverado HD can be outfitted with a 6.6L Duramax Turbo-Diesel V-8 paired with a 10-speed Allison automatic transmission. This mighty engine boasts 470 horsepower and 975 lb-ft of torque, along with a 36,000-lb maximum towing capacity and 6,638-lb maximum payload capacity.

Just because this engine is big and beefy, doesn’t mean it’s loud and disruptive. It’s engineered with sound absorption materials and a tuned air induction system that help keep it quiet, creating a comfortable and peaceful ride. The maintenance requirements are comparable to those of gasoline engines, and every 6.6L Duramax engine is backed by a 5-year/100,000-mile limited warranty to provide peace of mind and protection for the owner.

Chevy’s two diesel engines are engineered to deliver exceptional power, efficiency, and durability, making them ideal for both everyday driving and heavy-duty applications.
